Satoshi's Treasure

On April 15th, 2019, a message was received via the Blockstream Satellite kicking off the start of a Bitcoin treasure hunt.

Full text of initial message.

The messages pointed to a webpage which is the main hub for the hunt.

Main site: https://satoshistreasure.xyz/

The Prize

According to the message, the prize is a large amount of Bitcoin:

it is Bitcoin … in an amount equal to 1 million USD.

The address is unknown, but expected to be revealed soon.

How the Hunt Works

The private key to the Bitcoin address with the funds has been split into one thousands secrets using Shamir's Secret Sharing. The first to find 400 of these secrets can recreated the private key and take the funds. From the original message:

I have shattered this Bitcoin treasure into one thousand pieces, using the splitting magic of the wizard Shamir. To reassemble it, you or your clan must find exactly four hundred of the pieces, and meld them back together using Shamir's spell of recombination. Once you have done so, the treasure will be irrevocably yours.

We know there was a trial run of Satoshi's Treasure held at MIT in March 2019, and they used the ssss tool to split and recombine the secrets.

It seems likely this same method is used in the real hunt, as indicated in this Tweet:

Those were test runs, but anyone who played in those understands how to win :)

Unfortunately it appears that we cannot verify that a secret is a part of the treasure address, according to this Tweet:

Caveat: At least for the cryptography I helped you with (which was my only involvement in this so far), there isn't yet a protocol to verify the shares are of particular Bitcoin private key. And even if there was, nothing says you didn't keep another copy aside from trust

[[keys|Keys]]

Only three keys have been announced on the site thus far. The Jade Key, Bismuth Key, and Mamoru's Key.
